The execution, when arrives to that point
RapidMiner.init();
File f = new File("Trust.xml");
try {
Process process = new Process(f);
process.run();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XMLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Gives me that error:
<operator name="ModelLoader" class="ModelLoader">
<parameter key="model_file" value="C:\Algoritmo definitivo\model.mod"/>
</operator>
Can anyone help me?
